An apparent decade-old version of Grand Theft Auto VI's world is now explorable inside Grand Theft Auto V, giving fans an unusual look at how Rockstar's next open world may have evolved long before release.
Kotaku reports that map files in a newly public cache appear to date from around 2015 and were built or tested in GTA 5's engine. Community members have since loaded the rough assets into GTA 5 and begun comparing them with locations visible in newer GTA 6 material.
The broad outline is recognizable as Rockstar's Florida-inspired state of Leonida, but the early version is far from a reliable guide to the finished game. Roads, settlements and terrain differ across community comparisons, while large areas look unfinished or assembled from low-detail pieces. Rockstar has not published a complete official map.
An old leak gets a much wider audience
The files do not appear to come from a newly reported intrusion. Insider Gaming says the roughly 192GB archive originated with Rockstar's 2022 breach and circulated among a smaller group before spreading more widely in September 2026.
Most of that archive concerns GTA 5, including abandoned single-player content and a canceled Liberty City project. The GTA 6 material is a smaller part of the cache, but making the early terrain explorable has turned an opaque development artifact into something fans can directly compare with Rockstar's newer footage and screenshots.
That comparison still needs a large warning label. Notebookcheck notes that none of the material has been independently verified. Dataminers have also cautioned that some files may be simplified LOD geometry, the low-detail models games use for distant scenery, rather than a complete map from a playable build.
Rockstar has publicly identified Vice City, the Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia and Mount Kalaga National Park as major parts of GTA 6's setting. The company's official page lists a Nov. 19, 2026 release for PlayStation 5 and Xbox Series X|S. Until then, the leaked prototype is best read as a reported snapshot of development, not a promise of every location in the finished game.
